Mercedes-Benz filed this with NHTSA as a service bulletin dated Mar 11, 2026, about the structure. It names 10 model years (2022–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint Wind noises in the area of the mirror triangle on the front doors/side window panes Cause Potential causes: • Adjustment of the side window panes • Adjustment of the doors • Influence of seals • Influence of assembly Remedy • If the wind noises only occur on one side: Perform comparison of right/left of the window and door adjustment • If necessary, correct window and door adjustment according to WIS. For the windows, observe the insertion depth in the Z position and the Y position on the mirror triangle in particular. • Check inner seal for deformations. To do so, observe attachment 1 and attachment 2. If a deformation (waviness) can be ascertained: Replace seal or reform back into place using heat and fix in place using cold. • Check outer sealing rail to vertical sealing lip of the mirror triangle. To do so, observe attachment 3. If the sealing rail collides with the vertical sealing lip of the mirror triangle: Either route it such that it rests above the vertical sealing lip of the mirror triangle or shorten. • Check external sealing rail for correct assembly. To do this, ensure that it is engaged into the three existing mounting straps on the door. See Attachment 4. Also ensure that the outer sealing rail is correctly positioned in the x-direction and closes off flush. See Attachments 5 and 6 for this. Also ensure during assembly that the outer sealing rail is inserted beneath the mirror triangle. See Attachment 7. • Check the inner seal, especially in the mirror triangle area, for correct assembly. See Attachment 8.

A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI67.30-P-080343 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the LI67.30-P-080343 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
Which vehicles does LI67.30-P-080343 cover?
The manufacturer filed it against 10 model years: 2026 Mercedes-Benz AMG GT, 2025 Mercedes-Benz AMG GT, 2024 Mercedes-Benz AMG GT, 2026 Mercedes-Benz SL-Class, 2025 Mercedes-Benz SL-Class, 2024 Mercedes-Benz SL-Class and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
